I'd say the Elastic Beanstalk with a single container is very easy... zip your project with a Dockerfile, and it will create the container...

However, man that Awsrunfile or whatever it is called, and the two versions that are incompatible with the different EB versions, and it's painful... the hosted container solution equally so.

GC's docs and tools just seem so much more straight forward (as do Azure's for that matter).
